移植Python3到TQ2440（一）
2024-06-12 00:13:43
平台
硬件：TQ2440 64MB内存 256MB NandFlash
bootloader：U-Boot 2015.04
kernel：linux-4.9
Python: Python-3.6.0
工具链：arm-none-linux-gnueabi-gcc 4.8.3
概述
现在树莓派很火，在树莓派上面用户可以通过Python来控制板子上面的GPIO资源， 然后我想TQ2440也应该做到这一点。 将来根文件系统会通过NFS的方式挂载到开发板上面。

一、工具链
登录这个网址：http://www.veryarm.com/arm-none-linux-gnueabi-gcc
我们这里使用的是最新的Linux解压版：arm-2014.05-29，由于TQ2440用的arm9属于armv4t架构，所以在编译运行于TQ2440上的程序的时候需要给工具链传递参数-march=armv4t，为了简单起见，我们可以用下面的办法：
1 ( pengdl@ubuntu | ~/Study/cross_compile/arm-2014.05/bin | Remote:True ) 2 $ls -l 3 total 22581248 4 lrwxrwxrwx 1 pengdl pengdl 32 Apr 19 19:53 arm-linux-addr2line -> arm-none-linux-gnueabi-addr2line* 5 lrwxrwxrwx 1 pengdl pengdl 25 Apr 19 19:54 arm-linux-ar -> arm-none-linux-gnueabi-ar* 6 lrwxrwxrwx 1 pengdl pengdl 25 Apr 19 19:54 arm-linux-as -> arm-none-linux-gnueabi-as* 7 lrwxrwxrwx 1 pengdl pengdl 26 Apr 19 19:54 arm-linux-c++ -> arm-none-linux-gnueabi-c++* 8 lrwxrwxrwx 1 pengdl pengdl 30 Apr 19 19:54 arm-linux-c++filt -> arm-none-linux-gnueabi-c++filt* 9 lrwxrwxrwx 1 pengdl pengdl 26 Apr 19 19:54 arm-linux-cpp -> arm-none-linux-gnueabi-cpp* 10 lrwxrwxrwx 1 pengdl pengdl 25 Apr 19 19:55 arm-linux-cs -> arm-none-linux-gnueabi-cs* 11 lrwxrwxrwx 1 pengdl pengdl 32 Apr 19 19:55 arm-linux-cs-daemon -> arm-none-linux-gnueabi-cs-daemon* 12 lrwxrwxrwx 1 pengdl pengdl 30 Apr 19 19:55 arm-linux-elfedit -> arm-none-linux-gnueabi-elfedit* 13 -rwxrwxr-x 1 pengdl pengdl 57 Apr 19 20:00 arm-linux-g++* 14 -rwxrwxr-x 1 pengdl pengdl 57 Apr 19 20:06 arm-linux-gcc* 15 -rwxrwxr-x 1 pengdl pengdl 63 Apr 19 20:02 arm-linux-gcc-4.8.3* 16 lrwxrwxrwx 1 pengdl pengdl 29 Apr 19 19:56 arm-linux-gcc-ar -> arm-none-linux-gnueabi-gcc-ar* 17 lrwxrwxrwx 1 pengdl pengdl 29 Apr 19 19:56 arm-linux-gcc-nm -> arm-none-linux-gnueabi-gcc-nm* 18 lrwxrwxrwx 1 pengdl pengdl 33 Apr 19 19:57 arm-linux-gcc-ranlib -> arm-none-linux-gnueabi-gcc-ranlib* 19 lrwxrwxrwx 1 pengdl pengdl 27 Apr 19 19:57 arm-linux-gcov -> arm-none-linux-gnueabi-gcov* 20 lrwxrwxrwx 1 pengdl pengdl 26 Apr 19 19:57 arm-linux-gdb -> arm-none-linux-gnueabi-gdb* 21 lrwxrwxrwx 1 pengdl pengdl 28 Apr 19 19:57 arm-linux-gprof -> arm-none-linux-gnueabi-gprof* 22 lrwxrwxrwx 1 pengdl pengdl 25 Apr 19 19:57 arm-linux-ld -> arm-none-linux-gnueabi-ld* 23 lrwxrwxrwx 1 pengdl pengdl 25 Apr 19 19:58 arm-linux-nm -> arm-none-linux-gnueabi-nm* 24 lrwxrwxrwx 1 pengdl pengdl 30 Apr 19 19:58 arm-linux-objcopy -> arm-none-linux-gnueabi-objcopy* 25 lrwxrwxrwx 1 pengdl pengdl 30 Apr 19 19:58 arm-linux-objdump -> arm-none-linux-gnueabi-objdump* 26 lrwxrwxrwx 1 pengdl pengdl 29 Apr 19 19:58 arm-linux-ranlib -> arm-none-linux-gnueabi-ranlib* 27 lrwxrwxrwx 1 pengdl pengdl 30 Apr 19 19:58 arm-linux-readelf -> arm-none-linux-gnueabi-readelf* 28 lrwxrwxrwx 1 pengdl pengdl 27 Apr 19 19:58 arm-linux-size -> arm-none-linux-gnueabi-size* 29 lrwxrwxrwx 1 pengdl pengdl 30 Apr 19 19:58 arm-linux-strings -> arm-none-linux-gnueabi-strings* 30 lrwxrwxrwx 1 pengdl pengdl 28 Apr 19 19:58 arm-linux-strip -> arm-none-linux-gnueabi-strip* 31 -rwxr-xr-x 1 pengdl pengdl 736300 May 30 2014 arm-none-linux-gnueabi-addr2line* 32 -rwxr-xr-x 2 pengdl pengdl 763504 May 30 2014 arm-none-linux-gnueabi-ar* 33 -rwxr-xr-x 2 pengdl pengdl 1253360 May 30 2014 arm-none-linux-gnueabi-as* 34 -rwxr-xr-x 2 pengdl pengdl 687056 May 30 2014 arm-none-linux-gnueabi-c++* 35 -rwxr-xr-x 1 pengdl pengdl 734604 May 30 2014 arm-none-linux-gnueabi-c++filt* 36 -rwxr-xr-x 1 pengdl pengdl 686128 May 30 2014 arm-none-linux-gnueabi-cpp* 37 -rwxr-xr-x 1 pengdl pengdl 186548 May 30 2014 arm-none-linux-gnueabi-cs* 38 -rwxr-xr-x 1 pengdl pengdl 2186780 May 30 2014 arm-none-linux-gnueabi-cs-daemon* 39 -rwxr-xr-x 1 pengdl pengdl 24692 May 30 2014 arm-none-linux-gnueabi-elfedit* 40 -rwxr-xr-x 2 pengdl pengdl 687056 May 30 2014 arm-none-linux-gnueabi-g++* 41 -rwxr-xr-x 2 pengdl pengdl 686128 May 30 2014 arm-none-linux-gnueabi-gcc* 42 -rwxr-xr-x 2 pengdl pengdl 686128 May 30 2014 arm-none-linux-gnueabi-gcc-4.8.3* 43 -rwxr-xr-x 1 pengdl pengdl 23608 May 30 2014 arm-none-linux-gnueabi-gcc-ar* 44 -rwxr-xr-x 1 pengdl pengdl 23576 May 30 2014 arm-none-linux-gnueabi-gcc-nm* 45 -rwxr-xr-x 1 pengdl pengdl 23576 May 30 2014 arm-none-linux-gnueabi-gcc-ranlib* 46 -rwxr-xr-x 1 pengdl pengdl 307000 May 30 2014 arm-none-linux-gnueabi-gcov* 47 -rwxr-xr-x 1 pengdl pengdl 4484452 May 30 2014 arm-none-linux-gnueabi-gdb* 48 -rwxr-xr-x 1 pengdl pengdl 805164 May 30 2014 arm-none-linux-gnueabi-gprof* 49 -rwxr-xr-x 2 pengdl pengdl 1200784 May 30 2014 arm-none-linux-gnueabi-ld* 50 -rwxr-xr-x 2 pengdl pengdl 747500 May 30 2014 arm-none-linux-gnueabi-nm* 51 -rwxr-xr-x 2 pengdl pengdl 912812 May 30 2014 arm-none-linux-gnueabi-objcopy* 52 -rwxr-xr-x 2 pengdl pengdl 1109932 May 30 2014 arm-none-linux-gnueabi-objdump* 53 -rwxr-xr-x 2 pengdl pengdl 763504 May 30 2014 arm-none-linux-gnueabi-ranlib* 54 -rwxr-xr-x 1 pengdl pengdl 420160 May 30 2014 arm-none-linux-gnueabi-readelf* 55 -rwxr-xr-x 1 pengdl pengdl 737260 May 30 2014 arm-none-linux-gnueabi-size* 56 -rwxr-xr-x 1 pengdl pengdl 736332 May 30 2014 arm-none-linux-gnueabi-strings* 57 -rwxr-xr-x 2 pengdl pengdl 912812 May 30 2014 arm-none-linux-gnueabi-strip*
即在原来的工具链上面做一些软连接，对arm-linux-gcc/g++/gcc-4.8.3做一些特殊处理：
1 $cat arm-linux-gcc 2 #!/bin/bash 3 arm-none-linux-gnueabi-gcc -march=armv4t $* 4 5 $cat arm-linux-g++ 6 #!/bin/bash 7 arm-none-linux-gnueabi-g++ -march=armv4t $* 8 9 $cat arm-linux-gcc-4.8.3 10 #!/bin/bash 11 arm-none-linux-gnueabi-gcc-4.8.3 -march=armv4t $*
此外， 还需要注意的是， 将来在制作用于TQ2440的根文件系统的时候拷贝的工具链的lib库的位置：
arm-2014.05/arm-none-linux-gnueabi/libc/armv4t/lib
而不是：
arm-2014.05/arm-none-linux-gnueabi/libc/lib
这个用于高于armv4t架构的平台，如exynos4412用的是armv7架构。
二、Bootloader
使用的uboot可以到https://github.com/pengdonglin137/u-boot下载，可以参考：
u-boot-2015.04 在tq2440上的移植（使用spl引导u-boot）
将来的分区稍有变化:
| 1MB SPL |
1MB UBOOT |
1MB PARAMS |
5MB KERNEL |
1MB DTB | 247MB ROOTFS |
由于将来采用NFS挂载根文件系统启动的方式，下面是bootargs以及bootcmd：
bootargs：
noinitrd root=/dev/nfs rw nfsroot=192.168.1.101:/nfsroot/rootfs ethmac=1C:6F:65:34:51:7E ip=192.168.1.6:192.168.1.101:192.168.1.1:255.255.255.0::eth0:off init=/linuxrc console=ttySAC0,115200n
这里板子的IP是192.168.1.6，HOST的IP是192.168.1.101， 当然由于采用了设备树的方式， 所以也可以不在uboot里设置bootargs，而是放到设备树的chosen节点当中。
bootcmd：
nand read 0x300080000x3000000x500000; nand read 0x320000000x8000000x100000; bootm 0x30008000-0x32000000
这里会了加快启动速度， 提前把uImage和dtb文件少些到的nandflash中， 关于在tq2440上面支持dtb，请参考 讓TQ2440也用上設備樹（1）
三、kernel
可以到https://github.com/pengdonglin137/linux-4.9下载，tq2440_dt分支， 使用方法参考 讓TQ2440也用上設備樹（1）
烧写kernel和dtb到nand中：
1 烧写kernel： 2 mw.b 0x30008000 0xff 0x500000 3 tftp 0x30008000 uImage 4 nand erase 0x300000 0x500000 5 nand write 0x30008000 0x300000 0x500000 6 7 烧写dtb： 8 mw.b 0x30008000 0xff 0x100000 9 tftp 0x30008000 dtb 10 nand erase 0x800000 0x100000 11 nand write 0x30008000 0x800000 0x100000
四、Python

交叉编译Python-2.7.13到ARM（aarch32）—— 支持sqlite3
交叉编译Python-3.6.0到aarch64/aarch32 —— 支持sqlite3
由于上面两篇博文采用的是qemu模拟的cortex-a9平台，属于armv7架构，而我们的tq2440是armv4架构，所以需要做一些修改。
SQlite
1 #!/bin/bash 2 3 ../sqlite-autoconf-3170000/configure --host=arm-none-linux-gnueabi \ 4 --prefix=`pwd` \ 5 CFLAGS="-march=armv4t" \ 6 CPPFLAGS="-march=armv4t" \ 7 LDFLAGS="-march=armv4t" 8 9 make -j4 10 make install
Readline
1 #!/bin/bash 2 3 ../readline-7.0/configure --host=arm-none-linux-gnueabi \ 4 --prefix=`pwd` \ 5 CFLAGS="-march=armv4t" \ 6 CPPFLAGS="-march=armv4t" \ 7 LDFlAGS="-march=armv4t" 8 9 make -j4 10 make install
Termcap
配置:
1 #!/bin/bash 2 3 ../termcap-1.3.1/configure --host=arm-none-linux-gnueabi \ 4 --prefix=`pwd`
修改Makefile：
1 CC = arm-none-linux-gnueabi-gcc 2 AR = arm-none-linux-gnueabi-ar 3 RANLIB = arm-none-linux-gnueabi-ranlib 4 ... ... 5 CFLAGS = -g -march=armv4t
然后 make && make install
Python3
配置：
1 #!/bin/bash 2 3 ../Python-3.6.0/configure \ 4 --host=arm-linux \ 5 --build=armv4 \ 6 --prefix=`pwd` \ 7 --enable-ipv6 \ 8 --enable-shared \ 9 ac_cv_file__dev_ptmx="yes" \ 10 ac_cv_file__dev_ptc="no" \ 11 LDFLAGS="-L/home/pengdl/Study/tq2440/Python/SQlite/tq2440/lib \ 12 -L/home/pengdl/Study/tq2440/Python/Readline/tq2440/lib \ 13 -L/home/pengdl/Study/tq2440/Python/Termcap/tq2440" \ 14 CPPFLAGS="-I/home/pengdl/Study/tq2440/Python/SQlite/tq2440/include \ 15 -I/home/pengdl/Study/tq2440/Python/Readline/tq2440/include"
别忘了修改Modules/Setup文件，然后执行 make && make install即可。
五、根文件系统
参考博客 用Qemu搭建aarch32学习环境
下面是制作根文件系统的脚本：
1 #!/bin/bash 2 3 sudo rm -rf rootfs 4 sudo rm -rf tmpfs 5 sudo rm -rf ramdisk* 6 7 sudo mkdir rootfs 8 sudo cp ../busybox-1.24.2/_install/* rootfs/ -raf 9 10 sudo mkdir -p rootfs/proc/ 11 sudo mkdir -p rootfs/sys/ 12 sudo mkdir -p rootfs/tmp/ 13 sudo mkdir -p rootfs/root/ 14 sudo mkdir -p rootfs/var/ 15 sudo mkdir -p rootfs/mnt/ 16 17 sudo cp etc rootfs/ -arf 18 sudo mkdir -p rootfs/lib 19 20 sudo cp -arf /home/pengdl/Study/cross_compile/arm-2014.05/arm-none-linux-gnueabi/libc/armv4t/lib/*.so* rootfs/lib 21 22 #Python3 23 sudo mkdir -p rootfs/usr 24 pushd rootfs/usr 25 sudo cp -raf /home/pengdl/Study/tq2440/Python/Python3/tq2440/lib . 26 sudo cp -raf /home/pengdl/Study/tq2440/Python/Python3/tq2440/include . 27 sudo cp -raf /home/pengdl/Study/tq2440/Python/Python3/tq2440/bin . 28 sudo cp -raf /home/pengdl/Study/tq2440/Python/Python3/tq2440/share . 29 sudo arm-none-linux-gnueabi-strip lib/python* 30 popd 31 32 #sqlite3 33 sudo cp -raf /home/pengdl/Study/tq2440/Python/SQlite/tq2440/bin/* rootfs/bin 34 sudo cp -raf /home/pengdl/Study/tq2440/Python/SQlite/tq2440/include/* rootfs/include 35 sudo cp -raf /home/pengdl/Study/tq2440/Python/SQlite/tq2440/lib/* rootfs/lib 36 sudo cp -raf /home/pengdl/Study/tq2440/Python/SQlite/tq2440/share/* rootfs/usr/share 37 sudo arm-linux-strip rootfs/bin/sqlite3 38 39 #readline 40 sudo cp -raf /home/pengdl/Study/tq2440/Python/Readline/tq2440/include/* rootfs/include 41 sudo cp -raf /home/pengdl/Study/tq2440/Python/Readline/tq2440/lib/* rootfs/lib 42 43 sudo rm -f rootfs/lib/libwv* rootfs/lib/libuniconf* 44 sudo rm -f rootfs/lib/*.a 45 sudo rm -f rootfs/lib/*.la 46 sudo arm-none-linux-gnueabi-strip rootfs/lib/* 47 48 sudo mkdir -p rootfs/dev/ 49 sudo mknod rootfs/dev/tty1 c 4 1 50 sudo mknod rootfs/dev/tty2 c 4 2 51 sudo mknod rootfs/dev/tty3 c 4 3 52 sudo mknod rootfs/dev/tty4 c 4 4 53 sudo mknod rootfs/dev/console c 5 1 54 sudo mknod rootfs/dev/null c 1 3 55 56 sudo rm /nfsroot/rootfs_bak -rf 57 sudo mv /nfsroot/rootfs /nfsroot/rootfs_bak 58 sudo cp ./rootfs /nfsroot/ -raf
其中的etc目录可以到这里下载：http://files.cnblogs.com/files/pengdonglin137/etc.zip
